1. In a large skillet, cook beef and onion over medium heat until the meat is no longer pink; drain.
2. Stir in the tomatoes, green pepper, 4 Tbsp water, salt, chili powder and spaghetti. Bring to a boil. Reduce heat; cover and simmer for 30 minutes or until spaghetti is tender, stirring frequently and adding remaining water if necessary.
3. Sprinkle with cheese; cover and heat until cheese is melted, about 5 minute

Robyn's notes: it was good but not exciting, though being easy basically made up for that.
